one of my neighbors was a surrogate twice (I think in each case 3 eggs implanted - 2 sets of twins)

While she is DONE performing that service, I can ask her if she would be willing to discuss it from her perspective, if you want to try to put your friends together with her via email(we are in CT - so laws may be similar)

For her - if i recall correctly - she enjoyed the experience, had two VERY different sets of parents each time, waited forever in one situation for the egg donor to be picked...lots of anecdotes I am sure.
